Abstract:

Growth of organic product demand result in increasing organic fertilizer
demand. Two problem in producing organic fertilizer are long time producing and
poor quality fertilizer. Chicken manure and banana trunk are rich in nutrient. They
can be used as good material for compost producing. MOL tapai is activator to
shorten compost producing times. This research is to know the effect of MOL tapai
with different concentration to compost quality. This research consisted of two steps.
First step was compost producing and step two is plantation test. The data from
compost producing were analyzed with using completely randomized block design.
The data from plantation test were are analyzed using completly randomized factorial
design. Result showed that MOL tapai concentration didn’t affect pH, N, P, K of
compost, but affect C quality. Plantation test showed that dosage of fertilizer affect
plant height, leaf quantity, stem dryed weight, and root dryed weight. It is concluded
that MOL tapai additions at different levels relative does not affect the quality of
compost produced. The use of different dosages of very real effect on the
productivity of crop. The use dosage of 100 g gave the best growth response.
